* net: phy: micrel: fix too late link upChristian Hemp2018-04-121-0/+1
| | | | | | | | | | | | | | | | | | | | | Since commit a4cee7207a1 ("net: phy: micrel: Add workaround for bad autoneg") by Philipp Zabel <p.zabel@pengutronix.de>: Based on kernel commit d2fd719bcb0e ("net/phy: micrel: Add workaround for bad autoneg") by Nathan Sullivan <nathan.sullivan@ni.com>: Very rarely, the KSZ9031 will appear to complete autonegotiation, but will drop all traffic afterwards. When this happens, the idle error count will read 0xFF after autonegotiation completes. Reset the PHY when in that state. is it possible that we get the link to late and barebox reports "Network is down". The problem is that ksz9031_config_init is called again in an error case. In this case autoneg will restart but waiting for finish is missing. Signed-off-by: Christian Hemp <c.hemp@phytec.de> Tested-by: Stefan Müller-Klieser <s.mueller-klieser@phytec.de>
* net: phy: micrel: Do not overwrite reserved bitsSascha Hauer2016-11-081-1/+5
| | | | | | | | | | | | | | ksz8021_config_init() unconditionally sets the KSZPHY_OMSO_RMII_OVERRIDE bit. This is since the initial micrel phy commit, so it's not reproducible where this comes from and why this is done. Neither U-Boot nor the kernel ever touch this bit and so should we. Also, instead of doing a write only operation, read/modify/write the bit we actually want to change. This fixes operation on a KSZ8081MLX which is a MII only phy. KSZPHY_OMSO_RMII_OVERRIDE is reserved here and must be written to 0. KSZPHY_OMSO_MII_OVERRIDE is default 1 and must be written as 1. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* net: phy: micrel: KSZ9081/KSZ8091: Disable broadcast modeTeresa Remmet2016-05-131-1/+1
| | | | | | | | | KSZ9081 only supports two phy ids 0x0 and 0x3. 0x0 is also used as broadcast address. Disable broadcast, so that id 0x0 can be used as unique address on a shared bus. Signed-off-by: Teresa Remmet <t.remmet@phytec.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | Based on kernel commit 3c9a9f7fb0ee ("net/phy: micrel: Be more const correct") by Jaeden Amero <jaeden.amero@ni.com>: In a few places in this driver, we weren't using const where we could have. Use const more. In addition, change the arrays of strings in ksz9031_config_init() to be not only const, but also static.
